How to add/remove a Sub menuItem under the NSMenuItem

Question

How to add/remove a Sub MenuItem under the NSMenuItem dynamically at runtime?

Answer 1

I found a solution .

NSMenu  *mainMenu = [[NSApplication sharedApplication] mainMenu];
NSMenu  *appMenu = [[mainMenu itemAtIndex:5] submenu];

NSMenuItem *item=[[NSMenuItem alloc]initWithTitle:@"Tutorial" action:@selector(actionTutorial:) keyEquivalent:@"T"];

[item setTarget:self];
[item setTag:0];


[appMenu addItem:item];
[appMenu removeItemAtIndex:2]; // which is the index of above added item.
